Fitting the Radiator Valve
1. Inserting / replacing the batteries (Please note: before you change
the batteries, keep the valve completely open). Remove the
battery cover and insert the two batteries. Ensure that the
batteries are correctly inserted before use.
2. After installing the batteries, the screen will display the software
version, finally the symbol (TEST) will blink, and now the
connector will retract entirely. You can now mount the adapter.
(Note: Press any key to end the test after mounting the valve
adapter.)
